摘要： A process for the selective hydrodesulfurization of olefinic naphtha streams containing a substantial amount of organically bound sulfur and olefins. The olefinic naphtha stream is selectively hydrodesulfurized in a first sulfur removal stage and resulting product stream, which contains hydrogen sulfide and organosulfur is fractionated at a temperature to produce a light fraction containing less than about 100 wppm organically bound sulfur and a heavy fraction containing greater than about 100 wppm organically bound sulfur. The light fraction is stripped of at least a portion ofits hydrogen sulfide and can be collected or passed to gasoline blending. The heavy fraction is passed to a second sulfur removal stage wherein at least a portion of any remaining organically bound sulfur is removed.

摘要： A process for hydrodesulfurizing naphtha feedstreams wherein the reactor inlet temperature is below the dew point of the feedstock at the reactor inlet so that the naphtha will completely vaporize within the catalyst bed. It is preferred to use a catalyst comprised of about 1 to about 10 wt. % MoO.sub.3, about 0.1 to about 5 wt. % CoO supported on a suitable support material. They are also characterized as having an average medium pore diameter from about 60 .ANG. to 200 .ANG.. a Co/Mo atomic ratio of about 0.1 to about 1.0, a MoO.sub.3 surface concentration of about 0.5.times.10.sup.-4 to about 3.0.times.10.sup.-4 g MoO.sub.3 /m.sup.2, and an average particle size of less than about 2.0 mm in diameter.
